"Is 'I think, therefore I am' really correct?"
Haru asked Ren.
"Descartes' proposition," Ren nodded. "You have doubts?"
"Who is the 'I' that's thinking?"
Ren looked interested. "Good question. Self-referential."
"Is the I who thinks the same as the I who is thought about?"
"A problem philosophers have struggled with for millennia."
Haru opened her notebook. "How should I think about it?"
"First, let's break down the act of 'thinking,'" Ren wrote on the whiteboard.
"Thought process:
- Perceive something
- Judge it
- Draw conclusions"
"There's an 'I' performing this process?"
"We assume so. But is that true?"
Haru was confused. "I'm thinking, but I don't exist?"
"Thought exists, that's certain. But does a unifying 'I' exist?"
"But I'm here, now," Haru pointed at herself.
"That's the body," Ren distinguished. "Are body and thinking subject the same?"
"They're not?"
"Some philosophers say no. Thought is brain activity, but the sense of 'I' might be different."
Haru held her head. "Then what am I?"
"That's what philosophy explores."
"But I feel like I exist."
Ren smiled. "Phenomenology values that feeling. As undeniable experience."
"So I exist?"
"As experience, yes. But what that 'I' is remains mysterious."
Haru looked out the window. "The more I think, the less I understand."
"That's characteristic of self-reflection," Ren said. "When you try to observe, an observing subject appears. Infinite regress."
"No matter how far you go, there's an observer?"
"Yes. That's why 'I' can't be grasped."
Haru questioned. "So Descartes was wrong?"
"Not wrong. 'Thought exists' is certain. But 'I think' contains a leap."
"A leap?"
"From the existence of thought to the existence of a thinking subject. Might not be necessary."
Haru pondered. "Thought exists, but there's no 'I' doing it?"
"Close to Buddhism's 'no-self.'"
"No-self?"
"The idea that a fixed self doesn't exist."
Haru was surprised. "So I'm an illusion?"
"Not an illusion, more like a process," Ren explained. "Like a river. Always flowing. No fixed substance."
"But I feel like I'm the same person as yesterday."
"Memory creates continuity," Ren nodded. "But memory changes too. Not completely the same."
Haru laughed. "So the thinking me is a different person each moment?"
"In a sense."
"Isn't that scary?"
Ren said quietly. "Do you feel scared or free?"
"Free?"
"If there's no fixed self, you can always change."
Haru's eyes lit up. "I see. Not bound?"
"Not bound by your past self. You can freely choose your future self."
"But what about responsibility? Responsibility for past actions."
"Good point," Ren acknowledged. "Socially, we need to assume continuous self."
"So 'I' is a social construct?"
"In one aspect, yes."
Haru took a deep breath. "Difficult. Do I exist or not?"
"Maybe both," Ren smiled. "Depends on the level. Experientially, yes. Metaphysically, a mystery."
"Levels?"
"Practically, we assume 'I' exists. But philosophically, we keep questioning."
Haru wrote in her notebook. "The thinking I is an existence to be continually questioned."
"Good definition."
"So Ren, who are you?"
Ren laughed. "Good question. The answer, I'm still searching."
"Let's search together."
"Yes. That's the practice of philosophy."
They thought in silence. Who is the I that thinks? That question creates the I.
